Colonial Placement Behaviors Of Metabus Gravidus (Araneidae), August 2005, Kent Melchiors Aug 2005

Colonial Placement Behaviors Of Metabus Gravidus (Araneidae), August 2005, Kent Melchiors

Monteverde Institute: Tropical Ecology and Conservation

Metabus gravidus (Araneidae: Araneae) is a parasocial orb-weaving spider. It lives in the forest understory of Costa Rica along small streams. Web silk and spinning is very expensive and the web needs to be placed strategically to obtain maximum benefits. This study investigated the relationship between M. gravidus web size and the location and position of the web over the stream as well as the openness of the web. Specifically, the study asked if larger M. gravidus webs had a preferential placement, as closer to the water or oriented in a certain direction, to maximize prey capture and minimize web …

Flow Reversal Events Increase The Abundance Of Nontroglobitic Fish In The Subterranean Rivers Of Mammoth Cave National Park, Kentucky, Michael Ruhl Aug 2005

Flow Reversal Events Increase The Abundance Of Nontroglobitic Fish In The Subterranean Rivers Of Mammoth Cave National Park, Kentucky, Michael Ruhl

Masters Theses & Specialist Projects

Mammoth Cave National Park (MCNP) is home to the longest cave system in the World and is dissected by the Green River, one of the most speciose watersheds on the continent. Cave springs create a direct aquatic link between subterranean waterways and the Green River. The history of these subterranean river systems is filled with eyewitness reports of various species of surface water (nontroglobitic) fishes, including introduced rainbow trout. This study documents the occurrence of Green River fish species in the cave system of MCNP. Four sites were sampled over a two year period using a variety of gears. In …

Proceed With Precaution: The Statutory, Legal, And Consumer Influence On Genetically Modified Foods In Canada, Alexander Singh Aug 2005

Proceed With Precaution: The Statutory, Legal, And Consumer Influence On Genetically Modified Foods In Canada, Alexander Singh

Canadian Journal of Law and Technology

Despite the majority of consumers’ health and environmental concerns, genetically modified organisms (GMOs) now form a regular part of Canadian society. Our system of regulatory approval introduces GMOs into agriculture, while our legal regimes deal with rights and responsibilities with respect to GMO, all while grocers and consumers sell, buy and eat genetically modified foods (GMFs) as part of their daily diet. With the increasing prominence of GMOs in our society, and the consistent debate over their safety, there is a need to inject precaution into the principles behind how these foods and crops enter, remain and spread in the …

A Study Of Manual Mine Clearance, Gichd Aug 2005

A Study Of Manual Mine Clearance, Gichd

Global CWD Repository

Manual mine clearance is the fundamental tenet of mine action, yet has never been thoroughly analysed. The GICHD has managed a study into manual mine clearance analysing the history, management, methodologies and systems in use, risk assessment and risk management of the process and product and costings of manual mine clearance programmes. The report published shows that, whilst safety has improved significantly since the early days of mine clearance, there are still room for improvements in many areas. The study identifies positive examples of innovation and novel techniques that improve productivity and ultimately value for the donor and end user …

Influence Of Neck-Rail Placement On Free-Stall Preference, Use, And Cleanliness, Cassandra B. Tucker, Daniel M. Weary, David Fraser Aug 2005

Influence Of Neck-Rail Placement On Free-Stall Preference, Use, And Cleanliness, Cassandra B. Tucker, Daniel M. Weary, David Fraser

Housing and Confinement of Farm Animals Collection

Three experiments examined how the presence of a neck rail at different heights and locations influenced dairy cattle behavior and stall cleanliness. Experiment 1 compared 4 levels of neck-rail height (102, 114, and 127 cm and no neck rail; presented at 160 or 180 cm from the curb) in a preference test. Cows (n = 10) showed no consistent preference based on neck-rail height, regardless of the horizontal position of the neck rail. When cows were restricted to each treatment in turn, however, time spent standing fully (with all 4 hooves) in the stall was least in the stall with …

The Development Of A Rigorous Sampling Methodology For A Long-Term Annual Index Of Recruitment For Finfish Species From South-Western Australia, Daniel J. Gaughan, Suzanne G. Ayvazian, G Nowara, M Craine Aug 2005

The Development Of A Rigorous Sampling Methodology For A Long-Term Annual Index Of Recruitment For Finfish Species From South-Western Australia, Daniel J. Gaughan, Suzanne G. Ayvazian, G Nowara, M Craine

Fisheries Research Reports

This study has determined the optimal strategies to achieve statistically robust indices of recruitment of five key finfish species in south-western Australia. For another two species such indices could not be established. The sampling strategies developed will initially focus on the most appropriate location, month, and lunar phase, after which fine-tuning of the sampling activity will be undertaken with respect to time of day, tide height, weather conditions etc. A significant outcome from the project is that five finfish species have a sampling strategy for recruits that can be utilized as a monitoring program for the recreational and commercial fisheries …

Physics & Astronomy Faculty Works

We report on four Chandra grating observations of the oblique magnetic rotator theta(1) Ori C (O5.5 V), covering a wide range of viewing angles with respect to the star's 1060 G dipole magnetic field. We employ line-width and centroid analyses to study the dynamics of the X-ray - emitting plasma in the circumstellar environment, as well as line-ratio diagnostics to constrain the spatial location, and global spectral modeling to constrain the temperature distribution and abundances of the very hot plasma. We investigate these diagnostics as a function of viewing angle and analyze them in conjunction with new MHD simulations of …

Development And Food Demand Changes: Production And Management Implications, Norman Rask, Kolleen Rask Aug 2005

Development And Food Demand Changes: Production And Management Implications, Norman Rask, Kolleen Rask

Economics Department Working Papers

Per capita food consumption and production changes during economic development are analyzed using a resource-based cereal equivalent measure. Diet up-grades to livestock products during economic development contribute to an increase in per capita food resource use by a factor of five or more. Food consumption changes are generally consistent across countries and are only marginally affected by a country’s food production resource base (land). Food consumption increases tend to exceed food production increases in early stages of development, leading to food import needs. In later stages of development, per capita food consumption stabilizes. Continued increases in production allow the closing …

Conflicts In Development: Tourism And The Cattle Industry In Brazil, Nicholas Sanchez, John F. O'Connell Aug 2005

Conflicts In Development: Tourism And The Cattle Industry In Brazil, Nicholas Sanchez, John F. O'Connell

Economics Department Working Papers

This paper challenges the conventional view that where there is a political elite, economic development will proceed along lines that sacrifice future generations for the benefit of the current ruling class. We find that shortfalls in the balance of payments will cause those in authority to promote activities that encourage tourism as a solution to balance of payments deficit. The vehicle for generating tourism is the provision of public goods. More traditional paths toward development particularly cattle ranching are displaced by tourist attractions. While motivated by myopic self-interest, the pursuit of public goods reduces the amount of debt transferred to …

The Species-Norm Account Of Moral Status, Scott Wilson Aug 2005

The Species-Norm Account Of Moral Status, Scott Wilson

Philosophy Faculty Publications

Many philosophers have argued against Singer’s claim that all animals are equal. However, none of these responses have demonstrated an appreciation of the complexity of his position. The result is that all of these responses focus on one of his arguments in a way that falls victim to another. This paper is a critical examination of a possible response to the full complexity of Singer’s position that derives from the work of Carl Cohen, Kathleen Wilkes, and F. Ramsey. On this response, a being’s moral status depends not on the capacities and abilities she does in fact have, but instead …

Management Of The Proposed South Coast Trawl Fishery. A Discussion Paper., Department Of Fisheries. Aug 2005

Management Of The Proposed South Coast Trawl Fishery. A Discussion Paper., Department Of Fisheries.

Fisheries Management Papers

In late 1987, the Minister approved a development plan for the South Coast Inshore Trawl Fishery (Fisheries Management Paper No. 13) and made a number of notices regulating trawling activities in the Recherche Archipelago. Fishing Boat Licences were subsequently ‘endorsed’ by reference to those notices. The development plan was declared to be for a period ending 31 December 1989, subject to extension for a further year if necessary. Despite the considerable interest in the fishery during 1986 to 1989, fishing results demonstrated that the economic returns were marginal and a number of operators withdrew from participation in the fishery (at …

Resting Potential–Dependent Regulation Of The Voltage Sensitivity Of Sodium Channel Gating In Rat Skeletal Muscle In Vivo, Gregory N. Filatov, Martin J. Pinter, Mark M. Rich Aug 2005

Resting Potential–Dependent Regulation Of The Voltage Sensitivity Of Sodium Channel Gating In Rat Skeletal Muscle In Vivo, Gregory N. Filatov, Martin J. Pinter, Mark M. Rich

Neuroscience, Cell Biology & Physiology Faculty Publications

Normal muscle has a resting potential of −85 mV, but in a number of situations there is depolarization of the resting potential that alters excitability. To better understand the effect of resting potential on muscle excitability we attempted to accurately simulate excitability at both normal and depolarized resting potentials. To accurately simulate excitability we found that it was necessary to include a resting potential–dependent shift in the voltage dependence of sodium channel activation and fast inactivation. We recorded sodium currents from muscle fibers in vivo and found that prolonged changes in holding potential cause shifts in the voltage dependence of …

Human Activity Mediates A Trophic Cascade Caused By Wolves, Mark Hebblewhite, Clifford A. White, Clifford G. Nietvelt, John A. Mckenzie, Tomas E. Hurd, John M. Fryxell, Suzanne E. Bayley, Paul C. Paquet Aug 2005

Human Activity Mediates A Trophic Cascade Caused By Wolves, Mark Hebblewhite, Clifford A. White, Clifford G. Nietvelt, John A. Mckenzie, Tomas E. Hurd, John M. Fryxell, Suzanne E. Bayley, Paul C. Paquet

Biological Sciences Faculty Publications

Experimental evidence of trophic cascades initiated by large vertebrate predators is rare in terrestrial ecosystems. A serendipitous natural experiment provided an opportunity to test the trophic cascade hypothesis for wolves (Canis lupus) in Banff National Park, Canada. The first wolf pack recolonized the Bow Valley of Banff National Park in 1986. High human activity partially excluded wolves from one area of the Bow Valley (low-wolf area), whereas wolves made full use of an adjacent area (high-wolf area). We investigated the effects of differential wolf predation between these two areas on elk (Cervus elaphus) population density, adult …

Factors Affecting Distribution And Abundance Of Aquatic Macroinvertebrates In Autumnal Wetlands In Mammoth Cave National Park, Kentucky, Usa, Jered Studinski Aug 2005

Factors Affecting Distribution And Abundance Of Aquatic Macroinvertebrates In Autumnal Wetlands In Mammoth Cave National Park, Kentucky, Usa, Jered Studinski

Masters Theses & Specialist Projects

Despite a recent surge of interest in temporary lentic systems, a strong theory linking the biota to its environment has not emerged. Data were collected from ten autumnal wetlands at Mammoth Cave National Park, Kentucky, U.S.A., in an effort to elucidate the environmental variables (EV's) that affected both between- and within-pond macroinvertebrate distribution and abundance. Canonical correspondence analyses performed with between-pond data failed to find strong relationships between the macroinvertebrates and EV's. Additionally, the theory that hydroperiod would effect richness did not apply to these ponds. Within-pond canonical correspondence analyses, however, yielded strong relationships. Further testing using regression analysis and …

P38 Mitogen-Activated Protein Kinase (Mapk) First Regulates Filamentous Actin At The 8-16-Cell Stage During Preimplantation Development., Andrew J M Paliga, David R Natale, Andrew J Watson Aug 2005

P38 Mitogen-Activated Protein Kinase (Mapk) First Regulates Filamentous Actin At The 8-16-Cell Stage During Preimplantation Development., Andrew J M Paliga, David R Natale, Andrew J Watson

Obstetrics & Gynaecology Publications

BACKGROUND INFORMATION: The MAPK (mitogen-activated protein kinase) superfamily of proteins consists of four separate signalling cascades: the c-Jun N-terminal kinase or stress-activated protein kinases (JNK/SAPK); the ERKs (extracellular-signal-regulated kinases); the ERK5 or big MAPK1; and the p38 MAPK group of protein kinases, all of which are highly conserved. To date, our studies have focused on defining the role of the p38 MAPK pathway during preimplantation development. p38 MAPK regulates actin filament formation through the downstream kinases MAPKAPK2/3 (MAPK-activated protein kinase 2/3) or MAPKAPK5 [PRAK (p38 regulated/activated kinase)] and subsequently through HSP25/27 (heat-shock protein 25/27). We recently reported that 2-cell-stage murine …

Analyses Of High Resolution Hyperspectral Imagery For Characterization Of Ponderosa Pine Woodlands, Cullen R. Robbins

School of Natural Resources: Dissertations, Theses, and Student Research

The Bessey Unit of the Nebraska National Forest is a planted ponderosa pine forest located in the Nebraska Sand Hills. Planted in the early 20th Century, it provides a unique opportunity to study the effects of ponderosa pine establishment on the surrounding grassland ecosystem and the effects of increasing pine density on the forest ecosystem. It has been hypothesized that there are key levels of canopy cover at which shifts in ecosystem function occur. The goal of this research was to use remotely sensed data to develop a reliable method for estimating canopy cover. More specifically, canopy cover was estimated …

Foraging Behavior And Seasonal Movements Of The Eastern Red Bat (Lasiurus Borealis) In Central Indiana, Brianne L. Everson Aug 2005

Foraging Behavior And Seasonal Movements Of The Eastern Red Bat (Lasiurus Borealis) In Central Indiana, Brianne L. Everson

All-Inclusive List of Electronic Theses and Dissertations

Twenty-four female Eastern red bats (Lasiurus borealis) were captured and tracked to foraging areas near the Indianapolis International Airport during the summers of2003 and 2004 with full foraging data obtained on 13. A series ofmulti-azimuth (3-7) triangulations was used to estimate the location of each bat throughout the night. Euclidean distance analysis was used to examine habitat use by L. borealis. These bats had smaller home ranges than previously noted as well as smaller home ranges than other species at this location. They foraged over woodlands, newly planted tree fields, open water, park and pasture lands more than predicted by …

Chlorella Virus-Encoded Deoxyuridine Triphosphatases Exhibit Different Temperature Optima, Yuanzheng Zhang, Hideaki Moriyama, Kohei Homma, James L. Van Etten

Hideaki Moriyama Publications

A putative deoxyuridine triphosphatase (dUTPase) gene from chlorella virus PBCV-1 was cloned, and the recombinant protein was expressed in Escherichia coli. The recombinant protein has dUTPase activity and requires Mg2+ for optimal activity, while it retains some activity in the presence of other divalent cations. Kinetic studies of the enzyme revealed a Km of 11.7 μ M, a turnover kcat of 6.8 s-1, and a catalytic efficiency of kcat/Km = 5.8 x 105 M-1 s-1. dUTPase genes were cloned and expressed from two other chlorella viruses …
